Definitions

  • the present invention relates to a railway wheel with a tread and a flange.
  • the invention has for its object to provide a railway wheel according to the preamble of claim 1, in which the above-mentioned problems in hardening are eliminated.
  • the hardening of the railway wheel according to the invention can completely or partially grasp the part of the wheel flange facing the tread and / or the tread.
  • An advantage of this hardening is that it can be done directly in connection with the mechanical processing of the tread of the wheel by turning or over-turning. Because of the concentration (bundling) of the laser beam, the depth and extent of the hardening can be varied within wide limits.
  • the energy supplied per unit area and time unit can be easily controlled and the depth of the hardened layer can be easily and precisely adapted to the requirements of the product with regard to hardness and wear resistance.
  • Hardening can also easily be done together with a later overturning of the wheel, and the invention can be applied both to one-piece wheels and to wheels with a shrunk-on rim.
  • the tread can also be fully or partially hardened.
  • Laser curing devices are available in many embodiments on the market.
  • the depth of hardening is different for different hardened parts of the part of the wheel flange facing the tread and possibly the tread.
  • smaller, separately hardened sections are arranged on the tread such that the friction between the wheel and The rail is large in the running direction of the wheel and small in the lateral direction (perpendicular to the running direction). This gives you a great grip length for the bike.
  • the figure shows part of a one-piece railway wheel (full wheel), but the invention can also be used for a wheel in which the outer radial part comprising the tread and the wheel flange consists of a shrunk-on ring.
  • the wheel disc is 1 and the wheel rim 2.
  • the wheel has a tread 4 and a wheel flange 3.
  • the section A from the radially outermost point of the wheel flange 3 to the transition of the wheel flange into the tread 4 or parts of this section A and possibly also the tread 4 or parts thereof are laser-hardened.
  • the entire section A of the wheel flange and also the tread 4 are laser-hardened, i. that is, the laser hardening extends over the entire section B.
  • the - seen with respect to the rail - the outside (C) of the wheel flange remains unhardened, since in the case of hardening there is a risk that the wheel flange will be damaged if the wheel over Turnouts or similar places roll away.
  • the laser hardening mentioned can be carried out in connection with turning and also overturning (re-turning) the tread and possibly the wheel flange, which is particularly advantageous in the latter case, since the previously hardened parts of the wheel are turned off during this process.
  • the depth and extent of the hardening during laser hardening can be varied within wide limits.
  • Laser hardening can be done in one operation by turning or turning the wheel or immediately after this operation.
  • the depth and / or extent of the hardening can be influenced, for example, by controlling the energy supplied per unit area and / or time unit, so that, for example, the depth of the hardened layer can be adapted to the requirements of the product with regard to hardness and wear resistance.
  • the distance between the device for laser hardening and the surface to be hardened can be varied, for example to control the degree of hardening. It is expedient to set the hardening device with a laser beam directed perpendicular to the surface, but this setting can also be varied.
  • the direction of lateral movement of the curing device can also be changed to influence the depth and extent of the curing.
  • the laser beam can also be aimed at and reflected by a mirror, wherein the hardening can be controlled by rotating and / or shifting the mirror.
  • the distance between the curing device and the surface can be varied from 0 to a larger value, but in the latter case losses occur due to heating of the air.
  • section labeled A in the figure is said to be hard, but the surface of the flange is generally not to be hardened. However, the tread or parts of the tread are also hardened in certain cases. Section C of the wheel flange is not hardened. Where the wear is very large, a particularly large depth of hardness can be provided, but the entire tread must not be hardened, since the entire tread would then be under tension.
  • the railway wheel according to the invention can be varied in many ways within the scope of the general inventive idea disclosed.
